PROBLEM TO BE SOLVED: To provide a railway vehicle body structure in which a manufacturing cost is reduced through configuring an end part underframe with a small number of components and simplifying manufacturing while satisfying strength, weight-saving and acoustic insulation improvement.SOLUTION: An underframe 4 is split into one central part underframe positioning at the central part in the longitudinal direction of the underframe 4 and two end part underframes positioning at the end parts in the longitudinal direction by two first lateral beams extending in the width direction of the underframe 4. Regarding the central part underframe, two side beams 113 extending in the longitudinal direction are jointed to the end parts of plural form materials with T-rib extending in the longitudinal direction and plural lateral beams are jointed to the lower surfaces of the form materials with T-rib. Regarding the end part underframes, the two side beams 113 extending in the longitudinal direction are jointed to the end parts of a hollow form material 128 extending in the longitudinal direction, and two middle beams 115 extending in the longitudinal direction and one cap beam extending in the width direction are jointed to the lower surface of the hollow form material 128.SELECTED DRAWING: Figure 3
【課題】強度、軽量化、遮音性向上を満足しながら、少ない部品点数で端部台枠を構成して、製作を単純化し、製作コストを低減した軌条車両構体を提供する。【解決手段】台枠4は、前記台枠4の幅方向に延伸する2つの第一横梁によって、前記台枠4の長手方向の中央部に位置する1つの中央部台枠と前記長手方向の端部に位置する2つの端部台枠とに分割され、前記中央部台枠は、前記長手方向に延伸する複数のTリブ付形材の端部に前記長手方向に延伸する2つの側梁113が接合されると共に、前記Tリブ付形材の下面に複数の横梁が接合されたものであり、前記端部台枠は、前記長手方向に延伸する中空形材128の端部に前記長手方向に延伸する2つの前記側梁113が接合されると共に、前記中空形材128の下面に前記長手方向に延伸する2つの中梁115と前記幅方向に延伸する1つの枕梁が接合された、ことを特徴とする。【選択図】図3
